摘要：

目的探究足姿指数(FPI)评分系统对我国足部姿势评价的信度和效度。
方法 2019年9月至10月,2名评定者(评定者1、评定者2)学习FPI-6评分系统,熟练后对15例20~40岁成年人双下肢的足部姿势进行评估,2名评定者同一天先后对所有受试者进行第1次测试;2周内,再由评定者1对受试者进行第2次测试。计算组内相关系数(ICC)进行重测信度和测试者间信度评价,采用MedCalc进行Bland-Altman绘图。采用Spearman相关系数评价量表的内容效度,采用因子分析评价量表的结构效度。
结果 FPI各项及总分的重测信度和测试者间信度的ICC均> 0.75。测试者间FPI评分的平均差值为-0.133,一致性限度为(-1.82, 1.55)。FPI各条目与总分均相关(P < 0.05);提取到3个公因子,累计贡献率达80%以上。
结论 FPI-6评分系统具有较好的信度和效度,可应用于中国人的足姿评估,对减少运动损伤、疾病预防及康复治疗有重要的指导意义。

Abstract:

Objective To explore the reliability and validity of Foot Posture Index (FPI) scoring system in evaluating foot posture in China.
Methods From September to October, 2019, two testers (tester 1, tester 2) evaluated the foot posture of 15 adult volunteers (30 legs) aged 20 to 40 years after mastering the FPI-6 scoring system. They were tested first by two testers on the same day, and after two weeks, they were retested by tester 1. The intra-group correlation coefficient (ICC) was calculated to evaluate the test-retest reliability and the inter-tester reliability, and the MedCalc was used to perform the Bland-Altman plot. The correlation between the scores of items and scale was analyzed with Spearman analysis, and the items were analyzed with factor analysis.
Results The ICC of the test-retest and inter-tester reliability of each item and total score of FPI were higher than 0.75. The mean difference in FPI scores between the testers was -0.133 and the limits of agreement was (-1.82, 1.55). All items scores were correlated with the total score (P < 0.05); three factors were extracted with the cumulative contribution more than 80%.
Conclusion The FPI-6 scoring system is reliable and valid, to evaluate foot posture for Chinese.

Key words: foot posture index, foot posture, reliability, validity
